Microorganisms are the engines that drive most marine processes. Ocean modelling must evolve to take their biological complexity into account. Marine microorganisms are crucial for ocean health.

Marine snow—a mixture of dead plankton, waste, mucus, and other organic material slowly sinking from the ocean’s surface—is an important, but poorly understood, part of the ocean carbon cycle. Credit: ...

Leopard seals are prehistoric, reptilian-looking marine predators often portrayed as scary villains in movies such as "Happy Feet" and "Eight Below," but little is known about their basic biology. The ...

Marine ecology encompasses the study of complex interactions among organisms and their environment in the world’s oceans. Central to advancing this field has been the adoption of stable isotope ...

Limited understanding of basic ocean processes is hindering progress in marine carbon dioxide removal, with the on-going commercialisation of some approaches “premature and misguided”. In a new paper, ...

Biological processes in seawater are dependent on the supply of a number of chemical elements that serve as nutrients and affected by others that may act as toxicants. Besides the major algal ...

As the world warms, sweeping changes in marine nutrients seem like an expected consequence of increased ocean temperatures. However, the reality is more complicated. New research suggests that ...

Learn how bacteria inside marine snow may dissolve shell minerals and influence how the ocean stores carbon.

Marine heatwaves can have a hidden impact on microscopic organisms in the ocean, a new study reveals. The research, published in Nature Communications, demonstrates how excessive temperatures can ...

Climate science is entering a phase of reassessment as new ocean data introduces nuances that challenge long-standing assumptions. While global temperatures continue to trend upward, researchers are ...
